Well, Steve Jackson regained the rights for those games late last year (along with the rest of The Fantasy Trip) and has expressed interest in reissuing both. (See http://www.sjgames.com/fantasytrip/.)

I had Kung Fu 2100 back in the ancient times before the oceans drank Atlantis. I remember very little about that game except that I tended to cheat and then rationalize it so I could win. Which was strange, since it was a single-player game.
